Revision of Prior Period Financial Statements In preparing the condensed consolidated financial statements as of and for the three and six months ended June 30, 2022, the Company identified errors in its previously issued financial statements whereby (a) certain expenses that were cost of subscription revenue related and cost of service revenue related were inaccurately classified as sales and marketing expenses on the consolidated statements of operations and comprehensive loss, (b) certain equipment under lease or held for lease was inaccurately classified as inventory on the consolidated balance sheets and a portion of the cash outflows related to the equipment under lease or held for lease were misclassified between operating and investing cash flows on the consolidated statements of cash flows, and (c) the vesting of warrants related to the Business Development Agreement disclosed in Note 16 were not accounted for accurately. The identified errors impacted the Company's previously issued 2020 annual financial statements, 2021 quarterly and annual financial statements, and quarterly financial statements for the three months ended March 31, 2022. The Company has made adjustments to the prior period amounts presented in these financial statements accordingly. Additionally, the Company has made adjustments to correct for other previously identified immaterial errors. The Company evaluated the errors and determined that the related impacts were not material

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Significant Accounting Policies The significant accounting policies and estimates used in preparation of the unaudited condensed consolidated financial statements are described in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2021, and the notes thereto, which are included in our Annual Report on Form 10-K for the year ended December 31, 2021. There have been no material changes to the Company’s significant accounting policies during the three months ended June 30, 2022 outside of the items as described below. Leases as a Lessee Prior to January 1, 2022, the Company accounted for leases in accordance with ASC 840, Leases . At lease inception, the Company determined if an arrangement was an operating or capital lease. For operating leases, the Company recognized rent expense, inclusive of rent escalation, on a straight-line basis over the lease term. Effective on January 1, 2022, the Company accounts for leases in accordance with ASC 842, Leases . At contract inception, the Company determines if an arrangement is or contains a lease. A lease conveys the right to control the use of an identified asset for a period of time in exchange for consideration. If determined to be or contain a lease, the lease is assessed for classification as either an operating or finance lease at the lease commencement date, defined as the date on which the leased asset is made available for use by the Company (when the Company is the lessee). Where the Company is the lessee, for each lease with a term greater than twelve months, the Company records a right-of-use asset and lease liability. A right-of-use asset represents the economic benefit conveyed to the Company by the right to use the underlying asset over the lease term. A lease liability represents the obligation to make lease payments arising from the use of the asset over the lease term. Lease liabilities are measured at lease commencement and calculated as the present value of the future lease payments in the contract using the rate implicit in the contract, when available. If an implicit rate is not readily determinable, the Company uses an incremental borrowing rate measured as the rate at which the Company could borrow, on a fully collateralized basis, a commensurate loan in the same currency over a period consistent with the lease term at the commencement date. Right-of-use assets are measured as the amount of the initial lease liability plus initial direct costs and prepaid lease payments, less lease incentives granted by the lessor. The lease term is measured as the noncancelable period in the contract, adjusted for any options to extend or terminate when it is reasonably certain the Company will extend the lease term via such options based on an assessment of economic factors present as of the lease commencement date. The Company elected the practical expedient to not recognize leases with a lease term of twelve months or less. Components of a lease are split into three categories: lease components, non-lease components, and non-components. The fixed and in-substance fixed contract consideration (including any consideration related to non-components) are allocated, based on the respective relative fair values, to the lease components and non-lease components. The Company has elected the practical expedient to account for lease and non-lease components together as a single lease component for all underlying assets and allocate all of the contract consideration to the lease component only. The Company’s operating leases are presented in the condensed consolidated balance sheet as operating lease right-of-use assets, classified as noncurrent assets, and operating lease liabilities, classified as current and noncurrent liabilities. Operating lease expense is recognized on a straight-line basis over the lease term. Variable costs associated with a lease, such as maintenance and utilities, are not included in the measurement of the lease liabilities and right-of-use assets but rather are expensed when the events determining the amount of variable consideration to be paid have occurred. Subscription Revenue - Leases as Lessor In addition to selling our products directly to customers, we also derive revenue from leasing our equipment, which we classify as subscription revenue. Lease terms are typically four years, generally do not include unilateral options by either the Company or our customer to extend, terminate or to purchase the underlying asset, and customers generally pay either a quarterly or annual fixed payment for the lease and maintenance elements over the contractual lease term. Equipment leases are generally classified as operating leases as they do not meet any of the sales-type lease criteria per ASC 842 and recognized ratably over the duration of the lease. There are no variable lease payments as a part of these arrangements. The accounting provisions we use to classify transactions as sales-type are: (i) whether the lease transfers ownership of the equipment by the end of the lease term, (ii) whether the lease grants the customer an option to purchase the equipment and the customer is reasonably certain to do so, (iii) whether the lease term is for the major part of the economic life of the underlying equipment, (iv) whether the present value of the lease payments, and any residual value guaranteed by the customer that is not already reflected in the lease payments, is equal to or greater than substantially all of the fair market value of the equipment at the commencement of the lease, and (v) whether the equipment is specific to the customer and of such a specialized nature that it is expected to have no alternative use to the Company at the end of the lease term. Leasing arrangements meeting any of these conditions are accounted for as sales-type leases and revenue attributable to the lease component is recognized in a manner consistent with product revenue and the related equipment is derecognized with the associated expense presented as a cost of revenue. Leasing arrangements that do not meet the criteria for classification as a sales-type lease will be accounted for as a direct-financing lease if the following two conditions are met: (i) the present value of the lease payments, and any residual value guaranteed by the customer that is not already reflected in the lease payments and any other third party unrelated to the Company, is equal to or greater than substantially all of the fair market value of the equipment at the commencement of the lease, and (ii) it is probable that the Company will collect the lease payments and amounts necessary to satisfy a residual value guarantee. Leasing arrangements that do not meet any of the sales-type lease or direct-financing lease classification criteria are accounted for as operating leases and revenue is recognized straight-line over the term of the lease. The Company considers the economic life of most of our products to be seven years. The Company believes seven years is representative of the period during which the equipment is expected to be economically usable by one or more users, with normal service, for the purpose for which it is intended. The unguaranteed residual value is estimated to be the value at the end of the lease term based on the anticipated fair market value of the units. The Company mitigates residual value risk of our leased equipment by performing regular management and maintenance, as necessary. Generally, lease arrangements include both lease and non-lease components. The lease component relates to the customer’s right-to-use the equipment over the lease term. The non-lease components relate to (1) distinct services, such as SaaS and maintenance, (2) any add-on accessories, and (3) installation and training. Installation and training are included in service revenue as described below, and add-on accessories are included in product revenue. Because the equipment, SaaS, and maintenance components of a subscription arrangement are recognized as revenue over the same time period and in the same pattern, the Company elected the practical expedient to aggregate non-lease components with the associated lease component and account for the combined component as an operating lease for all underlying asset classes. In the evaluation of whether the lease component (equipment) or the non-lease components associated with the lease component (SaaS and maintenance) is the predominant component, the Company determined that the lease component is predominant as we believe the customer would ascribe more value to the use of the security equipment than that of the SaaS and maintenance services. Therefore, the Company will account for the combined lease component under ASC 842. The equipment lease and SaaS/maintenance performance obligations are classified as a single category of subscription revenue in the condensed consolidated statements of operations and comprehensive loss. The installation and training services represent distinct services provided to customers. These activities are considered separate performance obligations to the customer and therefore are considered non-lease components. As installation and training services are performed prior to lease commencement, the timing and pattern of transfer for these services differ from that of the lease component (i.e., security hardware) and are not eligible to be combined. We exclude from variable payments all lessor costs that are explicitly required to be paid directly by a lessee on behalf of the lessor to a third party. Revenue related to leases entered into with related parties were $0.2 million and $0.3 million during the three and six months ended June 30, 2022, respectively. Installation and training are generally billed to the lessee as part of the lease contract billing, according to various contractual terms. The installation and training costs incurred by the Company are accounted for as a fulfillment cost and are included in the cost of services revenue in the condensed consolidated statements of operations and comprehensive loss. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), as subsequently amended (collectively “ASC 842”). The guidance amends the existing accounting standards for lease accounting, including requirements for lessees to recognize assets and liabilities related to long-term leases on the balance sheet and expanding disclosure requirements regarding leasing arrangements. For lessees, leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. Lessors are required to classify leases as a sales-type, direct financing, or operating lease. A lease is a sales-type lease if it effectively transfers control of the underlying asset to the lessee as indicated by any one of five criteria being met. All leases that are not sales-type or direct financing leases will be classified as operating leases. In July 2018, the FASB issued additional guidance, which offers a transition option to entities adopting ASC 842 in which entities can elect to apply the new guidance using a modified retrospective approach at the beginning of the year in which the new lease standard is adopted. The Company utilized this transition option whereby financial information for prior periods presented before the ASC 842 effective date will not be updated. In November 2019, the FASB issued ASU 2019-10 deferring the effective date for private entities (also applicable for public companies that qualify as emerging growth companies) for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. In June 2020, the FASB issued ASU 2020-05 which further defers the effective date for private entities for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company adopted this guidance effective January 1, 2022. ASC 842 provides several optional practical expedients in transition. The Company applied the ‘package of practical expedients’ which allow the Company to not reassess whether existing or expired arrangements contain a lease, the lease classification of existing or expired leases, or whether previous initial direct costs would qualify for capitalization under ASC 842. The adoption of ASC 842 resulted in the recognition of operating lease liabilities of $3.0 million and operating right-of-use assets of $2.5 million, along with the write-off of certain deferred rent balances of $0.5 million within the Company’s condensed consolidated balance sheets as of January 1, 2022. The adoption did not have a significant impact on the Company’s condensed consolidated statements of operations and comprehensive loss and condensed consolidated statements of cash flows. In December 2019, the FASB issued ASU 2019-12, Income Taxes (ASC 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which is intended to simplify various areas related to accounting for income taxes. ASU 2019 12 removes certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. For public entities the guidance is effective for annual reporting periods beginning after December 15, 2020 and for interim periods within those fiscal years. For non-public entities, the guidance is effective for annual reporting periods beginning after December 15, 2021 and for interim periods within years beginning after December 15, 2022, with early adoption permitted. The Company adopted this guidance effective January 1, 2022 and the adoption of this guidance did not have a material impact on its condensed consolidated financial statements and related disclosures. In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity , which simplifies and clarifies certain calculation and presentation matters related to convertible and equity and debt instruments. Specifically, ASU 2020-06 removes requirements to separately account for conversion features as a derivative under ASC Topic 815 and removing the requirement to account for beneficial conversion features on such instruments. ASU 2020-06 also provides clearer guidance surrounding disclosure of such instruments and provides specific guidance for how such instruments are to be incorporated in the calculation of Diluted EPS. The guidance under ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The Company adopted this guidance effective January 1, 2022 and the adoption of this guidance did not have a material impact on its condensed consolidated financial statements and related disclosures. Recently Issued Accounting Pronouncements The Company qualifies as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and has elected not to “opt out” to the extended transition related to complying with new or revised accounting standards, which means that when a standard is issued or revised and it has different application dates for public and nonpublic companies, the Company will adopt the new or revised standard at the time nonpublic companies adopt the new or revised standard and will do so until such time that the Company either (1) irrevocably elects to “opt out” of such extended transition period or (2) no longer qualifies as an emerging growth company. The Company may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for nonpublic companies. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments — Credit Losses (Topic 326) (“ASU 2016-13”). The new standard adjusts the accounting for assets held at amortized cost basis, including marketable securities accounted for as available for sale, and trade receivables. The standard eliminates the probable initial recognition threshold and requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net amount expected to be collected. For public entities except smaller reporting companies, the guidance is effective for annual reporting periods beginning after December 15, 2019 and for interim periods within those fiscal years. In November 2019, the FASB issued ASU No. 2019-10, which deferred the effective date for non-public entities and smaller reporting companies to annual reporting periods beginning after December 15, 2022, including interim periods within those fiscal years. Early application is allowed. The Company expects to adopt this guidance effective January 1, 2023, and it is currently evaluating the impact on its condensed consolidated financial statements and related disclosures. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers , which amends ASC 805 to add contract assets and contract liabilities to the list of exceptions to the recognition and measurement principles that apply to business combinations and to require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. The amendments in ASU 2021-08 are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years and should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the amendments is permitted, including adoption in an interim period. The Company expects to adopt this guidance effective January 1, 2023, and it is currently evaluating the impact on its condensed consolidated financial statements and related disclosures.

Business Combinations [Abstract]
Merger with NHIC and Related Transactions	Merger with NHIC and Related Transactions On July 16, 2021, we consummated the business combination (the “Merger”), contemplated by the Agreement and Plan of Merger, dated March 5, 2021, with NHIC Sub Inc. (“Merger Sub”), a wholly-owned subsidiary of NewHold Investment Corp. (“NHIC”), a special purpose acquisition company, which is our legal predecessor, and Evolv Technologies, Inc. dba Evolv Technology, Inc. (“Legacy Evolv”), as amended by that certain First Amendment to Agreement and Plan of Merger dated June 5, 2021 by and among NHIC, Merger Sub and Legacy Evolv (the “Amendment” and as amended, the “Merger Agreement”). Pursuant to the Merger Agreement, Merger Sub was merged with and into Legacy Evolv, with Legacy Evolv surviving the Merger as a wholly owned subsidiary of NHIC. Upon the closing of the Merger, NHIC changed its name to Evolv Technologies Holdings, Inc. Evolv Technologies Holdings, Inc. became the successor entity to NHIC pursuant to Rule 12g-3(a) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The transaction was accounted for as a “reverse recapitalization” in accordance with GAAP. Under this method of accounting, NHIC was treated as the “acquired” company for financial reporting purposes. This determination was primarily because subsequent to the Merger, Legacy Evolv’s shareholders have a majority of the voting power of the combined company, Legacy Evolv comprises all of the ongoing operations of the combined entity, Legacy Evolv comprises a majority of the governing body of the combined company, and Legacy Evolv’s senior management comprises all of the senior management of the combined company. Accordingly, for accounting purposes, this transaction was treated as the equivalent of Legacy Evolv issuing shares for the net assets of NHIC, accompanied by a recapitalization. The shares and net loss per common share, prior to the Merger, have been retroactively restated as shares reflecting the Exchange Ratio established in the Merger. The net assets of NHIC were recorded at historical costs, with no goodwill or other intangible assets recorded. Operations prior to the Reverse Recapitalization are those of Legacy Evolv. Evolv had previously indicated that it would list units (consisting of one share of common stock and one-half of one warrant) on Nasdaq under the ticker symbol EVLVU, in continuation of the listing of the units NHIC sold in its initial public offering on August 4, 2020 under the ticker symbol NHICU. In September 2021, our transfer agent separated the units into the component shares and warrants at the closing of the Merger, and as a result the Evolv units were not made eligible to settle through the facilities of The Depositary Trust Company. Accordingly, all trades in the units from July 19, 2021 (the first trading day after the completion of the Merger) until August 24, 2021 were settled between brokers in the shares and warrants underlying the units. Trading in ticker symbol EVLVU was halted on August 24, 2021, and no trades in the units were permitted or occurred since that date. The units were delisted from Nasdaq effective September 10, 2021. Upon closing of the Merger each share of NHIC Class B common stock issued and outstanding immediately prior to the effective time of the Merger, which totaled 10,391,513 shares held by the NHIC Initial Shareholders (“Initial Shareholders”), was automatically converted into one validly-issued share of our Class A common stock. In addition, pursuant to the Merger Agreement, certain Legacy Evolv Shareholders became entitled to receive up to 15,000,000 shares of Class A common stock as earn-out shares. Upon closing of the Merger: • all of 24,359,107 shares of Legacy Evolv’s Series A-1 convertible preferred stock were converted into an equivalent number of shares of Legacy Evolv common stock on a one-to-one basis; • all of 3,484,240 shares of Legacy Evolv’s Series A convertible preferred stock were converted into an equivalent number of shares of Legacy Evolv common stock on a two-to-one basis; • all of 34,129,398 shares of Legacy Evolv’s Series B-1 convertible preferred stock were converted into an equivalent number of shares of Legacy Evolv common stock on a one-to-one basis; and • all of 15,367,312 shares of Legacy Evolv’s Series B convertible preferred stock were converted into an equivalent number of shares of Legacy Evolv common stock on a one-to-one basis On the closing date of the Merger, each share of Legacy Evolv common stock then issued and outstanding was cancelled and the holders thereof in exchange received 94,192,534 shares of the Company’s Class A common stock, which is equal to 0.378 newly-issued shares of the Company’s Class A common stock for each share of Legacy Evolv common stock (the “Exchange Ratio”). All outstanding warrants exercisable for common stock in Legacy Evolv (other than warrants that expired, were exercised or were deemed automatically net exercised immediately prior to the Merger) were exchanged for warrants exercisable for the Company’s Class A common stock with the same terms and conditions except adjusted by the Exchange Ratio. All outstanding stock options of Legacy Evolv common stock, totaling 57,938,375 stock options, were cancelled and the holders thereof in exchange received options to receive 0.378 shares of the Company’s Class A common stock for a total of 21,891,254 stock options. The modification of the stock options to reflect the exchange ratio did not result in an incremental compensation expense upon closing of the Merger. Prior to the completion of the Merger, the Company entered into subscription agreements (collectively, the “PIPE Investment”) with certain parties subscribing for shares of the Company’s common stock (the “Subscribers”) pursuant to which the Subscribers agreed to purchase. Pursuant to the PIPE Investment, the Company issued 30,000,000 shares of common stock for a purchase price of $10.00 per share with gross proceeds of $300.0 million. The proceeds, net of redemptions, received from the Merger were $84.9 million and gross proceeds received from the PIPE investment were $300.0 million. Based on the number of shares of common stock outstanding on July 16, 2021 (in each case, not giving effect to any shares issuable upon exercise of warrants, options, or earn-out shares), Legacy Evolv shareholders owned approximately 92.7% of the common stock of the Company and NHIC shareholders owned approximately 7.3%.

During each of the three and six months ended June 30, 2022 and 2021, there were no transfers between Level 1, Level 2 and Level 3. Valuation of Contingent Earn-out Pursuant to the Merger Agreement, the Legacy Evolv shareholders, immediately prior to the Merger, were entitled to receive additional shares of the Company’s common stock upon the Company achieving certain milestones as described in Note 2 of our consolidated financial statements of our Annual Report on Form 10-K for the year ended December 31, 2021. The Company’s contingent earn-out shares were recorded at fair value as contingent earn-out liability upon the closing of the Merger and are remeasured each reporting period. As of June 30, 2022, no milestones have been achieved. The fair value of the contingent earn-out is calculated using a Monte Carlo analysis in order to simulate the future path of the Company’s stock price over the earn-out period. The carrying amount of the liability may fluctuate significantly and actual amounts paid may be materially different from the liability’s estimated value. The significant assumptions used in the Monte Carlo model as of June 30, 2022 were as follows: 95% expected stock price volatility, a drift rate of 3%, a 25% likelihood of change in control and a remaining term of 3.7 years. The following table provides a rollforward of the contingent earn-out liability (in thousands): December 31, 2021 $ 21,206 Change in fair value (2,509) June 30, 2022 $ 18,697 Valuation of Contingently Issuable Common Stock Prior to the Merger, certain NHIC shareholders owned 4,312,500 Founder Shares. 1,897,500 shares vested at the closing of the Merger, 517,500 shares were transferred back to NHIC and then contributed to Give Evolv LLC, and the remaining 1,897,500 outstanding shares shall vest upon the Company achieving certain milestones as described in Note 2 of our consolidated financial statements of our Annual Report on Form 10-K for the year ended December 31, 2021. The Company’s contingently issuable common stock was recorded at fair value as contingent shares on the closing of the Merger and are remeasured each reporting period. As of June 30, 2022, no milestones have been achieved. The fair value of the contingently issued common shares is determined using a Monte Carlo analysis in order to simulate the future path of the Company’s stock price over the vesting period. The carrying amount of the liability may fluctuate significantly and actual amounts paid may be materially different from the liability’s estimated value. The significant assumptions used in the Monte Carlo model as of June 30, 2022 were as follows: 95% expected stock price volatility, a drift rate of 3%, a 25% likelihood of change in control and a remaining term of 4.0 years.

Revenue Recognition and Deferred Revenue [Abstract]
Revenue Recognition	Revenue Recognition The Company recognizes revenue in accordance with Accounting Standards Codification 606 – Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In order to achieve this core principle, the Company applies the following five steps when recording revenue: (1) identify the contract, or contracts, with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when, or as, performance obligations are satisfied. The Company derives revenue from (1) subscription arrangements generally accounted for as operating leases under ASC 842 and (2) from the sale of products, inclusive of SaaS and maintenance and (3) professional services. The Company’s arrangements are generally noncancelable and nonrefundable after ownership passes to the customer for product sales and upon installation for subscriptions. Revenue is recognized net of sales tax.

Evolv Technologies, Inc. will be responsible for the delivery of the units, in addition to providing related services, such as installation, training, and maintenance. Consideration transferred to Evolv Technologies, Inc. for the related products and services may be in the form of common stock or cash. Shares of common stock may be sold to generate funds for the purposes of paying for the donated goods and services. The sales transactions between Evolv Technologies, Inc. and Give Evolv eliminate in consolidation.

An additional $2.0 million in gross proceeds were made available in December 31, 2020 upon achievement of the integration milestone, whereby the Company successfully created software utilizing the investor’s application programming interface. The 2020 Convertible Notes provided a conversion option whereby upon the closing of a Qualified Financing event, in which the aggregate gross proceeds of the issuance of preferred stock totaled at least $10.0 million, the notes would automatically convert into shares of the same class and series of capital stock of the Company issued to other investors in the financing at a conversion price equal to 80% of the price per share paid by the other investors. The conversion option met the definition of an embedded derivative and was required to be bifurcated and accounted for separately from the notes.

The difference between the initial carrying value of the notes and the stated value of the notes represented a discount that was accreted to interest expense over the term of the Convertible Notes using the effective interest method. This derivative liability was derecognized as of December 31, 2021 as the liability was settled pursuant to the closing of the merger. Interest expense related to the 2020 Convertible Notes totaled $0.1 million and $0.3 million for the three and six months ended June 30, 2021, respectively.

The conversion option met the definition of an embedded derivative and was required to be bifurcated and accounted for separately from the notes.

The difference between the initial carrying value of the notes and the stated value of the notes represented a discount that was accreted to interest expense over the term of the Convertible Notes using the effective interest method. This derivative liability was derecognized as of December 31, 2021 as the liability was settled pursuant to the closing of the Merger. In June 2021, the Company modified the 2021 Convertible Notes to grant the holders an additional 1,000,000 shares of NHIC common stock as further consideration upon the automatic conversion of the notes upon closing of the Merger. This modification of the notes resulted in an extinguishment and the Company recognized a loss on extinguishment of the 2021 Convertible Notes of $11.8 million. The $26.7 million carrying value of the notes at June 21, 2021 was derecognized and replacement notes with an initial carrying value of $29.6 million were recorded. Additionally, in the extinguishment accounting, a derivative liability of $19.2 million was recognized, which represents the value of the 1,000,000 NHIC shares as well as a bifurcated embedded derivative for the conversion option.

Income Taxes	Income TaxesDuring the three and six months ended June 30, 2022 and 2021, the Company did not record income tax provisions or income tax benefits due to the net loss before income taxes expected to be incurred for the year ending December 31, 2022, as well as the Company’s continued maintenance of a full valuation allowance against its net deferred tax assets, and the net loss before income taxes incurred for the year ended December 31, 2021.The Company’s tax provision and the resulting effective tax rate for interim periods is determined based upon its estimated annual effective tax rate (“AETR”), adjusted for the effect of discrete items arising in that quarter. The impact of such inclusions could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings or losses versus annual projections. In each quarter, the Company updates its estimate of the annual effective tax rate, and if the estimated annual tax rate changes, a cumulative adjustment is made in that quarter.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Nonrecourse Promissory Note with Officer In August 2020, the Company entered into a $0.4 million promissory note with an officer with the proceeds being used to exercise options for 1,469,366 shares of common stock at a price of $0.24 per share. The promissory note bore interest at the Wall Street Journal Prime Rate and was secured by the underlying shares of common stock that were issued upon the exercise of the stock options. The promissory note was treated as nonrecourse as the loan was only secured by the common stock issued from the exercise of the stock options. As such, (i) the underlying stock option grant was still considered to be outstanding and the shares of common stock were not considered issued and outstanding for accounting purposes until the loan was repaid in full or otherwise forgiven and (ii) no receivable was recorded for the promissory note on the Company’s condensed consolidated balance sheets. As such, the promissory note effectively extended the maturity date of the option grant for the life of the loan, this change is treated as a stock option modification. The incremental fair value from the stock option modification was deemed immaterial. The interest on this nonrecourse loan is also considered nonrecourse. As the Company has no intent to collect interest, no accrued interest was recorded. In June 2021, the Company agreed to repurchase 43,665 shares of common stock valued at $8.05 per share of common stock held by the officer of the Company. In exchange for the repurchase of the common stock by the Company, the $0.4 million promissory note held by the officer was considered repaid in full. Business Development Agreement with Finback In January 2021, the Company granted a warrant exercisable for 2,552,913 shares of common stock to Finback, a consulting group who is an affiliate of one of the Company’s shareholders, with performance-based vesting conditions which vest upon certain sales being met under a Business Development agreement which has a term of three years. During the three months ended June 30, 2022 and 2021, the Company recorded $0.6 million and $0.7 million, respectively, of stock-based compensation expense within sales and marketing expense for the 2021 Finback common stock warrants. During the six months ended June 30, 2022 and 2021, the Company recorded $0.8 million and $0.8 million, respectively, of stock-based compensation expense within sales and marketing expense for the 2021 Finback common stock warrants.

As of June 30, 2022, Finback can earn 283,926 earn-out shares subject to stock-based compensation, based on the achievement of certain milestones. During the three months ended June 30, 2022 and 2021, no stock-based compensation expense within sales and marketing expense for the earn-out shares allocated to Finback was recorded. During the six months ended June 30, 2022 and 2021, no stock-based compensation expense within sales and marketing expense for the earn-out shares allocated to Finback was recorded.

Accounting Changes and Error Corrections [Abstract]
Revision of Prior Period Financial Statements	Revision of Prior Period Financial StatementsAs discussed in Note 1, in preparing the condensed consolidated financial statements as of and for the three and six months ended June 30, 2022, the Company identified errors in its previously issued financial statements whereby (a) certain expenses that were cost of subscription revenue related and cost of service revenue related were inaccurately classified as sales and marketing expenses on the consolidated statements of operations and comprehensive loss, (b) certain equipment under lease or held for lease was inaccurately classified as inventory on the consolidated balance sheets and a portion of the cash outflows related to the equipment under lease or held for lease were misclassified between operating and investing cash flows on the consolidated statements of cash flows, and (c) the vesting of warrants related to the Business Development Agreement disclosed in Note 16 were not accounted for accurately. The identified errors impacted the Company's previously issued 2020 annual financial statements, 2021 quarterly and annual financial statements, and quarterly financial statements for the three months ended March 31, 2022. The Company has made adjustments to the prior period amounts presented in these financial statements accordingly.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). All share and per share amounts contained herein for periods prior to the Merger have been retroactively adjusted to give effect to the Exchange Ratio (as defined in Note 3), unless otherwise indicated.
Leases as a Lessee	Leases as a Lessee Prior to January 1, 2022, the Company accounted for leases in accordance with ASC 840, Leases . At lease inception, the Company determined if an arrangement was an operating or capital lease. For operating leases, the Company recognized rent expense, inclusive of rent escalation, on a straight-line basis over the lease term. Effective on January 1, 2022, the Company accounts for leases in accordance with ASC 842, Leases . At contract inception, the Company determines if an arrangement is or contains a lease. A lease conveys the right to control the use of an identified asset for a period of time in exchange for consideration. If determined to be or contain a lease, the lease is assessed for classification as either an operating or finance lease at the lease commencement date, defined as the date on which the leased asset is made available for use by the Company (when the Company is the lessee). Where the Company is the lessee, for each lease with a term greater than twelve months, the Company records a right-of-use asset and lease liability. A right-of-use asset represents the economic benefit conveyed to the Company by the right to use the underlying asset over the lease term. A lease liability represents the obligation to make lease payments arising from the use of the asset over the lease term. Lease liabilities are measured at lease commencement and calculated as the present value of the future lease payments in the contract using the rate implicit in the contract, when available. If an implicit rate is not readily determinable, the Company uses an incremental borrowing rate measured as the rate at which the Company could borrow, on a fully collateralized basis, a commensurate loan in the same currency over a period consistent with the lease term at the commencement date. Right-of-use assets are measured as the amount of the initial lease liability plus initial direct costs and prepaid lease payments, less lease incentives granted by the lessor. The lease term is measured as the noncancelable period in the contract, adjusted for any options to extend or terminate when it is reasonably certain the Company will extend the lease term via such options based on an assessment of economic factors present as of the lease commencement date. The Company elected the practical expedient to not recognize leases with a lease term of twelve months or less. Components of a lease are split into three categories: lease components, non-lease components, and non-components. The fixed and in-substance fixed contract consideration (including any consideration related to non-components) are allocated, based on the respective relative fair values, to the lease components and non-lease components. The Company has elected the practical expedient to account for lease and non-lease components together as a single lease component for all underlying assets and allocate all of the contract consideration to the lease component only. The Company’s operating leases are presented in the condensed consolidated balance sheet as operating lease right-of-use assets, classified as noncurrent assets, and operating lease liabilities, classified as current and noncurrent liabilities. Operating lease expense is recognized on a straight-line basis over the lease term. Variable costs associated with a lease, such as maintenance and utilities, are not included in the measurement of the lease liabilities and right-of-use assets but rather are expensed when the events determining the amount of variable consideration to be paid have occurred.
Subscription Revenue - Leases as Lessor	Subscription Revenue - Leases as Lessor In addition to selling our products directly to customers, we also derive revenue from leasing our equipment, which we classify as subscription revenue. Lease terms are typically four years, generally do not include unilateral options by either the Company or our customer to extend, terminate or to purchase the underlying asset, and customers generally pay either a quarterly or annual fixed payment for the lease and maintenance elements over the contractual lease term. Equipment leases are generally classified as operating leases as they do not meet any of the sales-type lease criteria per ASC 842 and recognized ratably over the duration of the lease. There are no variable lease payments as a part of these arrangements. The accounting provisions we use to classify transactions as sales-type are: (i) whether the lease transfers ownership of the equipment by the end of the lease term, (ii) whether the lease grants the customer an option to purchase the equipment and the customer is reasonably certain to do so, (iii) whether the lease term is for the major part of the economic life of the underlying equipment, (iv) whether the present value of the lease payments, and any residual value guaranteed by the customer that is not already reflected in the lease payments, is equal to or greater than substantially all of the fair market value of the equipment at the commencement of the lease, and (v) whether the equipment is specific to the customer and of such a specialized nature that it is expected to have no alternative use to the Company at the end of the lease term. Leasing arrangements meeting any of these conditions are accounted for as sales-type leases and revenue attributable to the lease component is recognized in a manner consistent with product revenue and the related equipment is derecognized with the associated expense presented as a cost of revenue. Leasing arrangements that do not meet the criteria for classification as a sales-type lease will be accounted for as a direct-financing lease if the following two conditions are met: (i) the present value of the lease payments, and any residual value guaranteed by the customer that is not already reflected in the lease payments and any other third party unrelated to the Company, is equal to or greater than substantially all of the fair market value of the equipment at the commencement of the lease, and (ii) it is probable that the Company will collect the lease payments and amounts necessary to satisfy a residual value guarantee. Leasing arrangements that do not meet any of the sales-type lease or direct-financing lease classification criteria are accounted for as operating leases and revenue is recognized straight-line over the term of the lease. The Company considers the economic life of most of our products to be seven years. The Company believes seven years is representative of the period during which the equipment is expected to be economically usable by one or more users, with normal service, for the purpose for which it is intended. The unguaranteed residual value is estimated to be the value at the end of the lease term based on the anticipated fair market value of the units. The Company mitigates residual value risk of our leased equipment by performing regular management and maintenance, as necessary. Generally, lease arrangements include both lease and non-lease components. The lease component relates to the customer’s right-to-use the equipment over the lease term. The non-lease components relate to (1) distinct services, such as SaaS and maintenance, (2) any add-on accessories, and (3) installation and training. Installation and training are included in service revenue as described below, and add-on accessories are included in product revenue. Because the equipment, SaaS, and maintenance components of a subscription arrangement are recognized as revenue over the same time period and in the same pattern, the Company elected the practical expedient to aggregate non-lease components with the associated lease component and account for the combined component as an operating lease for all underlying asset classes. In the evaluation of whether the lease component (equipment) or the non-lease components associated with the lease component (SaaS and maintenance) is the predominant component, the Company determined that the lease component is predominant as we believe the customer would ascribe more value to the use of the security equipment than that of the SaaS and maintenance services. Therefore, the Company will account for the combined lease component under ASC 842. The equipment lease and SaaS/maintenance performance obligations are classified as a single category of subscription revenue in the condensed consolidated statements of operations and comprehensive loss. The installation and training services represent distinct services provided to customers. These activities are considered separate performance obligations to the customer and therefore are considered non-lease components. As installation and training services are performed prior to lease commencement, the timing and pattern of transfer for these services differ from that of the lease component (i.e., security hardware) and are not eligible to be combined. We exclude from variable payments all lessor costs that are explicitly required to be paid directly by a lessee on behalf of the lessor to a third party. Revenue related to leases entered into with related parties were $0.2 million and $0.3 million during the three and six months ended June 30, 2022, respectively. Installation and training are generally billed to the lessee as part of the lease contract billing, according to various contractual terms. The installation and training costs incurred by the Company are accounted for as a fulfillment cost and are included in the cost of services revenue in the condensed consolidated statements of operations and comprehensive loss.
Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), as subsequently amended (collectively “ASC 842”). The guidance amends the existing accounting standards for lease accounting, including requirements for lessees to recognize assets and liabilities related to long-term leases on the balance sheet and expanding disclosure requirements regarding leasing arrangements. For lessees, leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. Lessors are required to classify leases as a sales-type, direct financing, or operating lease. A lease is a sales-type lease if it effectively transfers control of the underlying asset to the lessee as indicated by any one of five criteria being met. All leases that are not sales-type or direct financing leases will be classified as operating leases. In July 2018, the FASB issued additional guidance, which offers a transition option to entities adopting ASC 842 in which entities can elect to apply the new guidance using a modified retrospective approach at the beginning of the year in which the new lease standard is adopted. The Company utilized this transition option whereby financial information for prior periods presented before the ASC 842 effective date will not be updated. In November 2019, the FASB issued ASU 2019-10 deferring the effective date for private entities (also applicable for public companies that qualify as emerging growth companies) for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. In June 2020, the FASB issued ASU 2020-05 which further defers the effective date for private entities for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company adopted this guidance effective January 1, 2022. ASC 842 provides several optional practical expedients in transition. The Company applied the ‘package of practical expedients’ which allow the Company to not reassess whether existing or expired arrangements contain a lease, the lease classification of existing or expired leases, or whether previous initial direct costs would qualify for capitalization under ASC 842. The adoption of ASC 842 resulted in the recognition of operating lease liabilities of $3.0 million and operating right-of-use assets of $2.5 million, along with the write-off of certain deferred rent balances of $0.5 million within the Company’s condensed consolidated balance sheets as of January 1, 2022. The adoption did not have a significant impact on the Company’s condensed consolidated statements of operations and comprehensive loss and condensed consolidated statements of cash flows. In December 2019, the FASB issued ASU 2019-12, Income Taxes (ASC 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which is intended to simplify various areas related to accounting for income taxes. ASU 2019 12 removes certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. For public entities the guidance is effective for annual reporting periods beginning after December 15, 2020 and for interim periods within those fiscal years. For non-public entities, the guidance is effective for annual reporting periods beginning after December 15, 2021 and for interim periods within years beginning after December 15, 2022, with early adoption permitted. The Company adopted this guidance effective January 1, 2022 and the adoption of this guidance did not have a material impact on its condensed consolidated financial statements and related disclosures. In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity , which simplifies and clarifies certain calculation and presentation matters related to convertible and equity and debt instruments. Specifically, ASU 2020-06 removes requirements to separately account for conversion features as a derivative under ASC Topic 815 and removing the requirement to account for beneficial conversion features on such instruments. ASU 2020-06 also provides clearer guidance surrounding disclosure of such instruments and provides specific guidance for how such instruments are to be incorporated in the calculation of Diluted EPS. The guidance under ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The Company adopted this guidance effective January 1, 2022 and the adoption of this guidance did not have a material impact on its condensed consolidated financial statements and related disclosures. Recently Issued Accounting Pronouncements The Company qualifies as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and has elected not to “opt out” to the extended transition related to complying with new or revised accounting standards, which means that when a standard is issued or revised and it has different application dates for public and nonpublic companies, the Company will adopt the new or revised standard at the time nonpublic companies adopt the new or revised standard and will do so until such time that the Company either (1) irrevocably elects to “opt out” of such extended transition period or (2) no longer qualifies as an emerging growth company. The Company may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for nonpublic companies. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments — Credit Losses (Topic 326) (“ASU 2016-13”). The new standard adjusts the accounting for assets held at amortized cost basis, including marketable securities accounted for as available for sale, and trade receivables. The standard eliminates the probable initial recognition threshold and requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net amount expected to be collected. For public entities except smaller reporting companies, the guidance is effective for annual reporting periods beginning after December 15, 2019 and for interim periods within those fiscal years. In November 2019, the FASB issued ASU No. 2019-10, which deferred the effective date for non-public entities and smaller reporting companies to annual reporting periods beginning after December 15, 2022, including interim periods within those fiscal years. Early application is allowed. The Company expects to adopt this guidance effective January 1, 2023, and it is currently evaluating the impact on its condensed consolidated financial statements and related disclosures. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers , which amends ASC 805 to add contract assets and contract liabilities to the list of exceptions to the recognition and measurement principles that apply to business combinations and to require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. The amendments in ASU 2021-08 are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years and should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the amendments is permitted, including adoption in an interim period. The Company expects to adopt this guidance effective January 1, 2023, and it is currently evaluating the impact on its condensed consolidated financial statements and related disclosures.
